Embodiment 1

[0033] Ramie / cotton 50 / 50 knitted fabric, pineapple weave, 180g per square meter, using conventional scouring, bleaching and mercerizing, and rolling Queenset PSO-5500 produced by Japan Kotani Chemical Industry Co., Ltd. before the fabric enters the setting machine for setting. Durability Hydrophilic agent. The consumption of described hydrophilic agent is 30g / L, and the excess ratio is 80%. At a setting temperature of 180° C., setting was carried out in a setting machine for 60 s, and the setting machine was a POWER-LINE type stenter setting machine produced by Bruckner, Germany. Then the treated fabric is placed on the fabric conveying device of the spraying device, conveyed at a speed of 30m / min, and the fabric passing under it is sprayed with a working liquid containing fluorine-containing water-repellent finishing agent using a turntable nozzle. The fluorine-containing water-repellent finishing agent is Oleophobol CP-S, a non-ionic fluorine-containing water-repellent fin...

Embodiment 2

[0035] Pure polyester knitted fabric, 100dtex polyester DTY, woven into 160g / m by double knitting machine 2 After removing the oil stains by using the conventional scouring process, the fabric is hydrophilized with the PermaloseTM hydrophilic agent (polyether ester structure) produced by the British ICI company before entering the sizing machine. The hydrophilic agent accounts for the total weight of the fabric. 5%, dipping temperature 80 ℃, time 20min. The pH value of the dipping solution is 5, and the bath ratio is 25:1. Bake at 180°C for 100s in a Korean Nissin 3200 setting machine. Then the treated fabric is placed on the fabric conveying device of the spraying device, conveyed at a speed of 30m / min, and the non-ionic fluorine-containing water-repellent finishing agent Oleophobol CP produced by Huntsman is applied with a pressure nozzle of 0.8kg. -S concentration of 40g / L working solution 1.5ml / m 2 Finally, after baking at 180° C. (3-stage oven), the fabric obtained aft...

Embodiment 3

[0038] The unidirectional moisture transfer performance of the obtained fabric was evaluated using the following method.

[0039] Evaluation method 1: Determine the one-way moisture permeability of the fabric by comparing the size of the remaining water marks on the fabric.

[0040] A syringe with a larger needle or a pipette with a smaller caliber are used to simulate sweat droplets in order to produce smaller-sized droplets, which are added to the fabrics of embodiment 1 and embodiment 2 respectively. The side treated with the working solution and the side not treated with the working solution of the fluorine-containing water-repellent finishing agent. When the droplet is added to one side of the fabric treated with the working solution of the fluorine-containing water-repellent finishing agent, the visual observation shows that the droplet quickly penetrates to the other side of the fabric and remains on the fabric treated with the working solution of the fluorine-containin...

Abstract

The invention relates to a method for preparing a product with a one-way moisture-conducting function. The method comprises the following steps of: 1) performing hydrophilization pretreatment on a textile; and 2) spraying water repellent finishing agent-containing working solution on one face of the treated textile, so that liquid drops with diameter of 0.1 to 2mm and spacing of 0.1 to 2mm are formed on the face of the textile and the product with the one-way moisture-conducting function is obtained. Fabrics prepared by the method has the advantages of greatly reducing the using amount of a plurality of resources such as water, energy and the like and solving the environmental problems of pollution discharge and the like, along with the one-way moisture-conducting property.

Description

technical field [0001] The present invention relates to a method for preparing a product with unidirectional moisture transfer function. In particular, the present invention relates to a method of making fabrics with unidirectional moisture permeability. Background technique [0002] In recent years, with the development of the clothing industry, people are not limited to clothing styles but also focus more on the research and improvement of clothing fabrics that can bring people a sense of comfort. In particular, in order to provide comfortable and convenient sensory effects to the human body for a longer period of time, people have more and more stringent requirements for the selection of clothing fabrics and the functions of fabrics. Therefore, in the research on the improvement of the function of clothing fabrics, how to make the clothing fabrics have the function of moisture absorption and quick drying has also become one of the more important aspects. With the deepen...
